CELATUS is a simple Windows app I built to hide secret messages inside ordinary images. It uses LSB steganography to embed text into an image and lets you protect it with a passcode. You can easily hide, reveal, preview, and save your messages without dealing with complicated tools. It started as a project to learn steganography and grew into a tool I’m excited to share.
